Kubuntu Focus: Desktop Theme Guided Solution

Change the Theme

Use the directions below to change or reset the desktop theme. Use the Use desktop layout from theme option if you want to restore icons, widgets, and the panel to the default. If you want to restore only the default panel, please see the next section.

Open System Settings
Click on Appearance
Click on Global Theme
Click on Focus Default
OPTIONAL: Check Desktop and window layout
Click Apply

Sometimes the widgets and icons can appear out of place or incorrectly sized after changing a theme. This is a known bug. To fix this, repeat the above steps and toggle the Use desktop layout from theme button. Then press apply again.

Switch desktop themes using System Settings.

Hints Widget

Every Kubuntu Focus model comes with an 11-page Hints Widget. By default, the Hints Widget appears at the top-right corner of the desktop. It provides handy advice for both beginners and seasoned Linux veterans. Highlights include:

Model-specific Plasma Desktop shortcuts for tiling windows, switching desktops, or finding a lost mouse pointer.
Model-specific shortcuts for your hardware controls. Examples include brightness, volume, sleep, and screenshots.
A cheat sheet with commonly used Bash shell commands. Examples include finding files, troubleshooting network issues, and fixing permissions.
A Vim text editor quick reference. This brief-yet-thorough guide also shows how to exit vim.

Show Widget on Demand

Long press, then drag-and-drop the widget to the panel. This installs an icon in the panel that you can click on to view and interact with the widget.
To restore the widget to the desktop, right-click on the panel and select Enter Edit Mode. Then drag the icon from the panel back to the desktop. You can now exit edit mode. Then long-press on the widget icon to resize it.
An alternative way to restore the widget is to delete the icon from the panel and then use the To restore the widget step detailed in the next section.

Deleting and Restore Widget

To remove the widget, long-press on it until you see a trash can on the bottom-left corner and click on it.
To restore the widget, navigate to System Settings > Appearance and then select any of the six Focus themes. When presented with a pop-up that states “The following will be applied by this Global Theme,” make sure to check [x] Desktop and window layout and then click the [Apply] button. This will restore the original layout and the widget.

WARNING: Remember this CHANGES the theme and layout, overwriting any custom changes. It will also move desktop shortcuts and icons to their default locations.

Find commands and shortcuts with the Hints Widget.

Theme Selections

The Kubuntu Focus has 10 stock Global Themes. These include Breeze, Breeze Dark, Breeze Twilight, and Kubuntu. The default Global Theme is Focus Default and it uses a bottom panel like stock Kubuntu. The same layout is also available in Focus Light and Focus Twilight. There are also three "vertical" themes that maximize usable screen height by placing the panel on the side. These themes are called Focus Vertical, Focus Vertical Light, and Focus Vertical Twilight.

You can download and use a different theme by clicking on the Get New Global Themes button. While these themes can be fun and engaging, we recommend using one of the stock Global Themes for daily work, as these are actively updated and tested with your system.

Download new themes in System Settings. Only download themes from individuals you trust, as they may contain executable code.

Panel Reset

Use the directions below reset the panel to the default.

Right-click on the panel you wish to remove
Click Edit Panel...
Click Remove Panel
Right-click on the desktop
Click + Add Panel > Kubuntu Focus Default Panel

Reset the panel to the default using the Kubuntu Focus Default Panel option.

Troubleshooting

Q: I can move my cursor but clicks do not work. This occurs when using the default, KDE Plasma desktop. How can I resolve this?

A: This is relatively rare, but it does happen. It appears to be a bug somewhere between QT and Plasma because it has been reported on Intel and Nvidia graphics. Luckily, there is an easy work-around that restores clicks and takes just a few seconds:

Press [CTRL][ALT][F3].
Wait 2-5 seconds until you see a virtual terminal on one or more screens. This will be black with white text that prompts you to login.
On 24.04 LTS (Noble), press [CTRL][ALT][F2] to return to the KDE Plasma desktop.
On 22.04 LTS (Jammy), press [CTRL][ALT][F1] to return to the KDE Plasma desktop.
Clicks should now register.

Q: When I change the theme, sometimes the icons and widgets are out of place or incorrectly sized. What can I do to fix this?

A: See the solution found in the Change the Theme section immediately after the instructions.

Q: When I hover over an icon in my task bar on the panel, I see a thumbnail of the application. How do I turn this off?

A: Right click near an app icon in the panel (but not on top of one). Then select Configure icons-only taskbar. In the first, Appearance tab, uncheck the Show small window previews... option and then click Apply.
